Abstract: User Equipment (UE) procedures are provided for controlling channel quality measurements in Non-Terrestrial Networks (NTNs). One proposed solution adds an expected duration of time the UE is to be served by a NTN serving cell, referred to as Tservice, to the rules of channel quality measurements. Tservice represents the remaining time until the UE's serving cell will be replaced by another cell (i.e., the time until another satellite will take over the responsibility to cover the UE's location). In some embodiments, Tservice is added to the rules of channel quality measurements such that the UE does not have to measure neighbor cells if the Tservice is high enough for the current cell and current channel quality in the cell is sufficient. Or, even if Reference Signal Received Power (RSRP) of the current cell is sufficient, UE needs to measure if Tservice of the current cell is less than a threshold.
